2 out of 3 of ours are grades.
First is my husband's horse Apache. Draft cross of some sort. He was a Nurse Mare Orphan foal and all we know is that the farm he came from had "grey gaited stallions" and a lot of draft and draft cross mares. So who knows beyond that. His base color was a chestnut tobiano so I have guessed at Belgian X grey spotted saddle? Maybe? He stands at a big 15.2 hands - everyone is always thinking he is over 16 hands.
The other one is my 2 year old - Rascal. I answered an ad for a haflinger, and he is one of them that was there. I'm sure he is not purebred haflinger - if he even has any at all in him. He is about 14 hands right now but growing.
